Walton will process all of Elpidas specialty DRAM, which accounts for about 33% of the Japanese firms revenues, while Powertech will process all of Elpidas commodity DRAM, which accounts for about 61% of its revenues, Sakamoto said.
Sakamoto signed a partnership deal with Walton chairman Yu-heng Chiao yesterday, while signing the deal with Powertech today. Elpida currently outsources about 60% of its back-end processing, market sources indicated.
Elpidas monthly output is expected to reach 50-60 million 256Mbit-equivalent DRAM chips by the end of 2005, and the increased orders to the two Taiwan-based firms should help boost Taiwans overall orders for backend DRAM services 40% this year, according to the market sources.
Sakamoto did not say whether back-end processing of Elpidas DDR2 products would also be outsourced to Walton, but Yu revealed that his company might purchase more DDR2 testing equipment later this year.
Sakamoto expects prices for DDR products to continue their downward trend until the first quarter of 2006 as demand shifts to DDR2 chips. He expects DDR2 to become the mainstream memory product in the third quarter of 2005.
